CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of International Application No. PCT/CN2022/075335, filed Feb. 7, 2022, which claims priority to Chinese Patent Application No. 202110183790.1, filed Feb. 8, 2021. The entire contents of each of the above-referenced applications are expressly incorporated herein by reference.

TECHNICAL FIELD

The present application relates to the technical field of communications, and in particular, relates to a transmission link processing method and apparatus and a terminal.

BACKGROUND

A transmission link of a terminal usually includes a transceiver, a Power Amplifier (PA), a switch, a filter, an antenna, and the like. A signal output by the transceiver is amplified by the PA and sent by the antenna. The PA needs to be supplied with power. Due to the limitation of implementation, the PA cannot completely convert input power into output power. PA efficiency can be roughly defined as PAE=(Pout-Pin)/P_(DC), where Pout is output signal power of the PA, Pin is input signal power of the PA, and P_(DC) is DC power supply power of the PA.

During the process of implementing the present application, the inventors found that there are at least the following problems in related technologies:

Based on a PAE test result of the terminal, it can be seen that when the output signal power of the PA is low (for example, below 15 dBm), PAE<10%, which means that 90% of the power supplied to the PA is consumed. In other words, the related technology has the problem of low PA efficiency of the terminal, which leads to excessive power consumption and is undesirable for energy saving of the terminal.

With reference to the accompanying drawings, the following describes in detail the transmission link processing method in the embodiments of the present application based on embodiments and application scenarios.

As shown in FIG. 2 , an embodiment of the present application provides a transmission link processing method, where the transmission link includes: a transceiver and a power amplifier; and the method includes:

-   -   Step 201: A terminal determines a transmit power level of the         terminal according to power configuration information.     -   Step 202: The terminal controls, in a case that the transmit         power level of the terminal is a first transmit power level, a         signal output by the transceiver to not be amplified by the         power amplifier; otherwise, controls the signal output by the         transceiver to be amplified by the power amplifier.

At the first transmit power level, maximum output power of the terminal is less than a first threshold.

In this embodiment of the present application, the first transmit power level may also be referred to as a low transmit power level. For example, a current transmit power level of Uu includes: PC3 (23 dBm) or PC2 (26 dBm), which can also be called a second transmit power level or a high transmit power level. A current transmit power level of a sidelink (SL) is 23 dBm, which may also be called a second transmit power level or a high transmit power level. The first transmit power level may be called PC4, and at the first transmit power level, the maximum output power of the terminal is lower than the PC3 or PC2.

According to different application scenarios and implementation methods, the maximum transmit power of PC4 can be between 5 and 15 dBm, or the maximum transmit power of PC4 can be between 5 and 10 dBm, or the maximum transmit power of PC4 can be between 10 and 15 dBm. Corresponding first transmit power levels, such as PC4 Uu or PC4 SL, may be respectively defined on a Uu interface and an SL interface.

As shown in FIG. 3 and FIG. 4 , the transmission link of the terminal includes: a transceiver, a power amplifier PA, a first switch, a second switch, a filter, and an antenna. Switching of the first switch is used to control whether the signal output by the transceiver passes through the power amplifier PA.

As shown in FIG. 3 , when the terminal is configured to the first power transmission level (that is, the low power transmission level, such as PC4), the terminal controls the signal output by the transceiver to not be amplified by the power amplifier, that is, the signal output by the transceiver passes through the first switch, the second switch, and the filter and then is sent by the antenna. As shown in FIG. 4 , when the terminal is configured to the second power transmission level (that is, the high power transmission level, such as PC2 or PC3), the terminal controls the signal output by the transceiver to be amplified by the power amplifier, that is, the signal output by the transceiver passes through the first switch, the power amplifier, the second switch, and the filter, and then is sent by the antenna.

In some embodiments, the second configuration information includes:

-   -   a signal received quality threshold corresponding to each         transmit power level supported by the Uu interface, for example,         a Reference Signal Receiving Power (RSRP) threshold.

-   -   a transmit power level of the SL interface per cell; for         example, the network configures the same or different SL         transmit power levels for terminals in different cells or         different cell groups;     -   a transmit power level of the SL interface per terminal (per         UE); for example, the network configures the same SL transmit         power level for all bands of the terminal;     -   a transmit power level of the SL interface per frequency of the         terminal; for example, the network configures the same or         different SL transmit power levels for different frequencies of         the terminal;     -   a transmit power level of the SL interface per band of the         terminal; for example, the network configures the same or         different SL transmit power levels for different bands of the         terminal;     -   a transmit power level of the SL interface per BWP of the         terminal; for example, the network configures the same or         different SL transmit power levels for different BWPs of the         terminal;     -   a transmit power level of the SL interface per working carrier         of the terminal; for example, the network configures the same or         different SL transmit power levels for different carriers of the         terminal; or     -   a transmit power level of the SL interface per carrier group of         the terminal; for example, the network configures the same or         different SL transmit power levels for different carrier groups         of the terminal.

In at least one embodiment of the present application, if the power configuration information includes: third configuration information and/or third configuration information, step 201 includes:

-   -   determining, in a case that signal received quality of the         terminal is greater than the signal received quality threshold,         that the transmit power level of the Uu interface or the SL         interface of the terminal is the first transmit power level;     -   or     -   determining, in a case that signal received quality of the         terminal is less than the signal received quality threshold,         that the transmit power level of the Uu interface or the SL         interface of the terminal is the second transmit power level;         where at the second transmit power level, maximum output power         of the terminal is greater than a second threshold.

For example, the network configures the usage condition of the Uu transmit power level for the terminal, for example, configures an RSRP measurement threshold of the terminal as X dB. When the RSRP measurement result of the downlink signal measured by the terminal is greater than X dB, the low transmit power level PC4 can be used; otherwise, the high transmit power level such as PC2/PC3 can be used. The terminal switches the Uu power level according to the comparison between the RSRP measurement result and the threshold.

For another example, the network configures the usage condition of the SL transmit power level for the terminal, for example, configures an SL RSRP measurement threshold of the terminal as Y dB. When the RSRP measurement result of the SL signal measured by the terminal is greater than Y dB, the low transmit power level PC4_SL can be used; otherwise, the high transmit power level can be used. The terminal switches the power SL level according to the comparison between the SL RSRP measurement result and the threshold.

In some embodiments, the network directly configures the maximum transmit power level of the Uu interface of the terminal; for example, the maximum transmit power level of the terminal is configured as the low transmit power level PC4 according to the deployment scenario or the service requirements of the terminal.

For example, the network configures, according to the deployment form and coverage requirements (such as small cells and indoor cells), that all terminals with low power level capabilities in the network use the low transmit power level, for example, configures through system broadcast information. For another example, the network configures, according to actual service requirements, coverage requirements, and energy-saving requirements of the terminal, that terminals with low power level capabilities in the network use the low transmit power level, for example, configures through terminal-specific Radio Resource Control (RRC).

In some embodiments, the network directly configures the maximum transmit power level of the SL interface of the terminal; for example, may configure the SL maximum transmit power level of the terminal as the low transmit power level PC4_SL according to user service requirements.

For example, the network configures, according to the deployment form and coverage requirements, that all terminals with SL low power level capabilities in the network use the SL low transmit power level, for example, configures through system broadcast information. For another example, the network configures, according to actual service requirements, coverage requirements, and energy-saving requirements of the terminal, that terminals with SL low power level capabilities in the network use the SL low transmit power level, for example, configures through terminal-specific RRC.
